svn commit: r228879 - head/include

[Ed Schouten]

Author: ed
Date: Sun Dec 25 20:51:40 2011
New Revision: 228879
URL: http://svn.freebsd.org/changeset/base/228879

Log:
  Add <stdalign.h> and <stdnoreturn.h>.
  
  Even though these header files make little sense to me, they are part of
  the standard. By including these header files, you can simply use
  `alignas', `alignof' and `noreturn' instead of the underscore-prefixed
  versions.

Added:
  head/include/stdalign.h   (contents, props changed)
  head/include/stdnoreturn.h   (contents, props changed)
Modified:
  head/include/Makefile

Modified: head/include/Makefile
